Dynamic DNS vs Dedicated VPN IP (sh.itjust.works)

Hi everyone!

I'm looking into self-hosting, and I currently have dynamic DNS set up to point to my home IP.

My question: is it worth getting a dedicated IP through a VPN?

I'm pretty technically savvy, but when it comes to networking I lack practical experience. My thought is that pointing my domain to a dedicated IP and routing that traffic to my home IP would be safer - especially if I only allow traffic on certain ports from that IP. Just curious if that idea holds up in practice, or if it's not worth the effort.

No, it's inside the network. Once I'm inside my network via the VPN, the proxy server routes to the service I want based on the subdomain instead of using the IP and port as the address.

This can also be useful if, instead of going the VPN route, and you choose to go the CDN tunnel (for example, Cloudflare) way. I actually started with a tunnel via Cloudflare, but after some digging, I don't trust them anymore. Having a tunnel allows you to close all ports coming into your network, but at the expense of having to trust the tunnel provider, and I don't trust many companies out there.
